8 8.6-4 For a DSB-SC system with a channel noise PSD of Sn() 10-12 and a baseband signal of bandwidth 5 kHz, the receiver output SNR is required to be at least 47 dB. The receiver is as shown in Fig. 8.30. (a) What must be the signal power Si received at the receiver input? (b) What is the receiver output noise power No? (c) What is the minimum transmitted power Sr if the channel transfer function is He)10-3 over...

The input r(t) to a DSBSC receiver is a DSB signal s(t) = A m(t)cos (21fet) corrupted by additive white Gaussian noise with two-sided power spectral density N,/2, where No = 10-12 W/Hz, m(t) is a message signal bandlimited to 10 kHz. Average power of m(t) is Pm = 4 W and Ac = 2 mV. The block diagram of the receiver is shown below. Note that the receiver has filters which have slightly larger bandwidths than a typical DSB...
